A sweet helper script to add repo to /etc/apt/source.list along with gpg key import.

What we were doing in the earlier versions : {As an Example}

Step 1: On the PPA's overview page you'll see the PPA's OpenPGP key id. It'll look something like this: 1024/12345678. Copy it, or make a note of, the portion after the slash, e.g: 12345678.

Step 2: Open your terminal and enter:

sudo apt-key adv —keyserver keyserver.ubuntu.com —recv-keys 12345678

Replace 12345678 with the key id you copied in step 1.

Step 3: Finally, tell Ubuntu to re-load the details of each software archive it knows about:

sudo apt-get update

Now in karmic with the new helper script :

“

add-apt-repository ppa:ppa_name

That’s it this adds the ppa to source.list and also imports the keys.
